Pattern Proposal: Steering Context Projection

Summary

Compile repository changes and capabilities into structured prompt facts to steer agent decision-making.

Candidate Pattern

• ID: steering-context-projection
• Classification: intelligence
• Maturity: established
• Type: implemented

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/steering/models.py (PromptFact, SteeringRuntimeIndex, ArchitecturalDelta) - Typed projection models structuring agent input context
• .github/workflows/cas-build-steering-projection.yml - Orchestrates build of steering projection in CI

Scope Assessment

• Evidence Strength: high
• Confidence: high
• Applies to: ideas-to-life-cas

Rationale

• Intent: Transform raw Git diffs and repository capability graphs into compact factual inputs consumed by agent reasoning steps.
• Context: Raw codebase diffs are too noisy for direct agent prompts; agents need condensed architectural intent.
• Force: Context window saturation from raw diffs
• Force: Irrelevant file noise obscuring architectural impact
